Where does the powertrain control module come from?
The primary inputs to the PCM come from many sensors, of different types, that are spread around the car. Most of them are oriented toward engine management and performance. These sensors fail at a much higher rate than any of the computers do. Early use of the powertrain control module dates back to the late 1970s…
What is the name of the engine control module?
It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control Module (BCM), for a total of three separate computers. These automotive computers are generally very reliable.
Which is a symptom of a bad Powertrain Control Module?
The third symptom of a powertrain control module having issues is that the vehicle may not turn on or run properly. A bad PCM can cause the vehicle to not have any engine management control. Without any control, the engine won’t be able to start at all.
How many computers does a body control module have?
On some cars, such as many Chryslers, there are multiple computers: the PCM, the Transmission Control Unit, and the Body Control Module, for a total of three separate computers as an example. These automotive computers are generally very reliable.
What makes up a power train control module?
A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU).

Where is the Transmission Control Module on a car?
The transfer of power from the engine to the wheels. The transmission performs the main role in transferring that power and the module is the component that controls the transmission. You will find this little component on the rear side of the engine.
When to worry about a powertrain control module?
If a vehicle consumes more fuel than it should, this is a sign of the powertrain control module and the ECM having issues. If your engine is behaving erratically, like misfiring or stalling, then this could be an indication of a faulty powertrain control module or electronic control module.
